e With field and greenhouse season at a rest, winter is the time to tackle a number of chores

that ensure a successful season next year, which really is not far off. In fact, transplants will be started less than three months from now! The success of any transplant crop starts with a healthy greenhouse environment. This applies to flowering annuals such as impatiens, all the way to long season field vegetables such as Brussels sprouts. There are many factors involved in producing a healthy transplant: light, water quality, fertility, growing medium, and of course pest management.

The first step to managing pests in transplant production strives to prevent outbreaks. Sanita-tion is the first step and can be applied in many ways. Now is the time to clean the green-house of all plant material debris, remove all weeds, and sanitize with materials listed below. Although we don’t recommend reusing pots, if it is being done, they too should be cleaned and sanitized.

The disinfection of surfaces such as benches, glazing and structural components can reduce overwintering populations of insects (and mites) as well as sources of disease. There are a number of disinfectants available to commercial growers. Ammonium chloride materials such as Physan 20/20, GreenShield and Kleengrow are exclusively for sanitation of hard surfaces. Hydrogen peroxide applications of ZeroTol or Oxidate are also allowed for the surface of plants.

Often in greenhouse settings materials have different labels for ornamental and vegetable transplants. The above hydrogen peroxide materials illustrate this point. ZeroTol is labeled for flowers, while Oxidate is for vegetables. Although these have the same active ingredient, to be in compliance with NY pesticide law, each should be applied only to the crop specified on the label.

Specifically labeling insecticides and fungicides for ornamentals or vegetable transplants ap-plies as well. Given the opportunity for confusion, there is no substitution for studying the label. However, if you’d like to learn more about what is legal, effective and practical come to the Transplant session Tuesday, January 21, at the Empire State Producers Expo at the Oncenter in Syracuse, NY.

Soil management sessions on muck soils, reduced tillage and cover crops will be held Wednesday, January 22 at the 2014 Empire State Producers EXPO, Oncenter Convention Center, Syracuse. Nutrient management for vegetables on muck soils will be the focus at the 9 am Muck Soil session by renowned muck soil spe-cialist Darryl Warncke, Michigan State University. Both beginning and experi-enced muck growers will take something back to the farm from this talk.

The 1 pm Reduced Tillage session offers a new look at reduced tillage and cover crops for vegetables. Conservation Till-age Farmer Innovator Award winner Jesse Sanchez, farm manager of Sano Farms, Firebaugh, CA, introduced the soil conservation practices ten years ago in tomatoes and other crops on their 4,000 acre farm and has been an inspira-

Darryl Warncke, Professor of Soil Fertility & Plant Nutrition, Michigan State, will explain How cover crops affect nutrient management, so you can realize all the benefits they provide. Last but not least, Thomas Bjorkman, Cornell, will explain how you can Get the most out of a buck-wheat cover crop after early vegetables. Buckwheat can be super at crowding out weeds and preventing weed seed pro-duction.

tion to other CA growers ever since. Hear about the changes they made and the improvements they’ve seen in their crops. There will be a Reduced Tillage Grower Group Discussion following. Members of the Western NY and Central NY Groups, and all others interested, are invited to participate.

The Cover Crop session will kick off at 3:30 pm. Dave Robison, Legacy Seeds, Winona Lake, IN, and a founding mem-ber of the Midwest Cover Crop Council, will describe how Cover crops CAN bene-fit vegetable fields! More and more New York fields are getting cover cropped, primarily with grasses, but also with leg-umes, and even some crucifers and oth-er crops. Many vegetable growers aren’t making use of the significant amount of nitrogen those legumes are providing, however, by decreasing fertilizer rates.

After more than a decade and a half long drought from registrations of new chemistries for onion maggot control, a couple of new products finally became available.

1) FarMore® FI500, is a seed treatment from Syngenta with the active ingredient spinosad. It belongs to a completely different chemical class than Lorsban (a.i. chlorpyrifos) and Trigard (a.i. cyromazine) for managing onion maggot. Included in this seed treatment package is another insecticide, thiamethoxam and three fungicides for control of damp-ing off pathogens. Addition of Pro Gro is required for protection from onion smut. Far-More® OI100 is also now available, which contains only spinosad.

2) Sepresto® is a seed treatment combination of two neonicotinoids with a 3:1 ratio of clothianidin (same active as Poncho) and imidacloprid (same active as Gaucho and Ad-mire), which are both in the same chemical class as the thiamethoxam component in FarMore FI500. On Nunhem’s varieties, Sepresto is available as part of a seed treatment package, “CATS”, which includes three fungicides for control of damping off and onion smut. The fungicide for onion smut is thiram, not Pro Gro (a.i. thiram + carboxin); with-out carboxin, control of onion smut will not be as good. Nunhem’s will not treat with Pro Gro.

New in 2014 – Sepresto will be available on all onion varieties, not just on Nunhem’s varieties

Even though Bayer has opened Sepresto up to all varieties, treatment of other varieties with Sepresto would likely have to be a special order, as would treatment of Nunhem’s varieties with Farmore FI500.

BE CAUTIOUS WHEN USING SEPRESTO Historically, the active ingredient in Sepresto, clothianidin both alone and in combination with imidacloprid, has performed as well as Trigard + Lorsban in Cornell trials with an aver-age performance of 90% control in 13 trials from 2004 to 2009. Unexpectedly, in 2012 trials, Sepresto failed to provide adequate control of onion maggot (< 50% control) in 2 out of 3 studies, where onion maggot damage ranged from 21 to 83% in the untreated check. At the location where pressure was lowest, Sepresto gave 85% control.

Unfortunately, again in 2013, Sepresto failed to provide adequate control of onion maggot under high pressure (95% damage in the untreated). Despite this, we have only heard of one complaint of unsatisfactory performance with Sepresto from onion growers. It is our understanding that most growers have been using Sepresto in combination with chlorpyri-fos (i.e. Lorsban).

DOES USING CHLORPYRIFOS (LORSBAN) WITH SEPRESTO IMPROVE CONTROL? Sometimes, it depends if Lorsban works. The combination of Lorsban and Sepresto per-formed differently across our trials. At one site in 2012 where onion maggot pressure was high and Sepresto only gave 31% control, the combination with chlorpyrifos reduced pres-sure by 50%, which worked as well as chlorpyrifos by itself. At another site, where Sepres-to gave 43% control, the combination of chlorpyrifos and Sepresto had no effect. At the third site in 2012 and in the 2013 trial, the combination with chlorpyrifos also made no difference, because chlorpyrifos was not working at these sites, probably due to the devel-opment of resistance. Unfortunately, it does not appear that combining Sepresto with Lorsban is a reliable solution to the seemingly inconsistent performance of Sepresto, espe-cially when onion maggot pressure is high. This situation also illustrates the need to switch to new chemistries altogether.

Fortunately, we have Farmore FI500! The active ingredient in this seed treatment (spinosad) belongs to a completely different chemical class than Lorsban, Trigard and Sepresto. Farmore FI500 has consistently been one of the top performing treatments in all five of Cornell’s trials in 2012 and 2013 with an average performance of 79% control, which was comparable to Trigard + chlorpyrifos

(average 81%). Not once did we see a sig-nificant increase in control with the addi-tion of Lorsban, although numerically better control was achieved in 2 out of 5 trials. Therefore, we suggest using Far-More FI500 by itself in nearly all cases. The only exception would be in a field or portion of a field that has an annual history of high onion maggot damage.

RESISTANCE MANAGEMENT IS CRITICAL FOR LONGEVITY OF NEW SEED TREAT-MENTS Onion maggot is notorious for developing resistance to insecticides, including orga-nochlorines, carbamates and organophos-phates like chlorpyrifos (Lorsban) and probably also to Trigard (resistance never confirmed, but efficacy noticeably declined in many fields). However, Lorsban + Tri-gard has continued to be one of the best performing treatments in recent Cornell trials, despite not working that well when each product is used alone.

Onion maggot can develop resistance to an insecticide class within 4-5 years of contin-uous exposure. Once resistance to a chem-ical class has developed in an onion mag-got population, the population may be-come controllable again after eliminating exposure for a few years. This is the reason why we suggest rotating away from Tri-gard and chlorpyrifos, to reverse develop-ment of resistance to these materials. Hopefully, we can regain our confidence in Sepresto in the meantime and will be able to use it in 2 to 3-year rotations with Far-more FI500. Farmore FI500 may be used on Nunhem’s varieties. We understand that rotating chemical classes in every field in the entire state is not realistic, but…

Growers should at least strive to switch chemical classes after a maxi-mum of three years in a given field.

(This is a summary of information presented by Walter DeJong, Cornell potato breeder, at the November 6th Cornell Potato Variety/Line Show & Tell in Ithaca. Some New York potato certified seed growers may have seed, or very small quantities may be available from Cornell on request. Contact Carol MacNeil at crm6@cornell.edu or 585-394-3977 x406.) For the New York Certified Seed Potato 2013 Crop Directory, Grower Info and Varieties Grown, go to: http://cvp.cce.cornell.edu/crop.php?id=24)

The information presented below is based on numerous research trials conducted at Cornell farms around Ithaca, and in growers’ fields, by Walter DeJong and Don Hal-seth, Cornell. Photos are from the 2012 Potato Show & Tell, Canandaigua (Photos: C. MacNeil, CVP).

Waneta (NY138) (from a cross of Marcy x NY115 in 1998). Late maturity chipstock and tablestock. Large tubers, attractive shape, moderately textured skin. Tompkins County marketable yields over eleven years averaged 90% of Atlantic. Steuben and Wyoming County yields over ten years averaged 100% of Atlantic. Wayne County (muck soil) yield over five years averaged 100% of Atlantic. Moderate resistance to common scab. Resistant to race Ro1 of the golden nema-

tode. Vines start slow but develop well. Tuber size is similar to Atlantic. Large tubers have

shown 5-10% hollow heart (consider planting closer together). Less susceptible to blackspot bruise than Snowden. Long tuber dormancy; seven weeks longer than Atlantic (enabling storage/marketing into April, May). Specific gravity has averaged 0.010 less than Atlantic. Chip color out of 44°F storage has been very good: visual chip scores over nine years averaged 3.0 compared to 3.6 for Snowden (lower is better). In fifteen SFA trials Agtron scores averaged 65, compared to 63 for Snow-den.

NY141 (R6-4 x NY115, 1998). Early to mid sea-son tablestock, large, attractive tubers. Tompkins County marketable yields over

eleven years have averaged 99% of Atlantic. Early yield, the end of July in Ithaca, has been good, averaging 111% of Superior.

Wayne County (muck) yield over four years averaged 100% of Atlantic.

PA yield over seven years averaged 96%. Good resistance to common scab. Resistant

to race Ro1 of the golden nematode. Typically 2 to 3% of tubers have knobs. Has set an average of 7 tubers per foot, with

an average weight of 6.1 ounces. Tuber dormancy is about two weeks longer than Atlantic. Very good resistance to blackspot bruise. Specific gravity has averaged 0.011 less than Atlantic. Does not chip.

NY140 (NY121 x NY115, 1998). Late season; dual purpose chip and tablestock. High yields of large tubers; lightly textured skin. Note! Susceptible to common scab, comparable to Katahdin. Moderate resistance

to late blight as well as early blight in PA trials in 2007 - 2009. Resistant to races Ro1 and Ro2 of the golden nematode.

Tuber dormancy is about six weeks longer than Atlantic. Specific gravity has aver-aged 0.012 less than Atlantic (37 trials), which will limit where it could be grown for chips. Chip quality has generally been very good: over the past nine years it has averaged 3.5, comparable to Snowden.

NY148 (NY128 x Marcy, 2003). Late sea-son, high gravity chipstock. NOTE! Some heat necrosis, variable chip color, but has resistance to PVY, some resistance to early and late blight. Tompkins County yields over six years

averaged 112% of Atlantic. Wyoming and Steuben County yields

over five years averaged 96%. Good resistance to common scab to

date. Resistant to potato virus Y. Some resistance to early and late blight in PA in 2012. Resistant to race Ro1 of the golden nematode.

Tuber size is similar to Snowden. Scurfy tuber skin. In 2010, two-thirds of tubers exhibited internal necrosis in one yield trial. Heat necrosis has been observed on Long Island in 2013 and in trials in southern states. Tuber dor-mancy is comparable to Atlantic. Spe-cific gravity is high. Chip color from 44°F storage is variable and not as good as Snowden.

NY151 (NY121 x Salem, 2005). Late sea-son, white tablestock with relatively smooth skin. Has been in trials fewer years than other lines listed here. Tompkins County marketable yields

over four years averaged 105% of Atlantic.

Long Island yield was 117% of Reba in two years.

Moderate resistance to common scab. Resistant to race Ro1 of the golden nematode.

Low levels of defects. Specific gravity is low. Tubers do not slough apprecia-bly after boiling. Tuber dormancy is comparable to Atlantic.

Acetochlor herbicide products received registration approval in New York in February 2013 providing New York growers with a valuable new tool and an expanded array of options for weed control. A chloroacetamide herbicide, acetochlor is already widely used across the United States for weed control in corn and is consistently effective for control of grasses and small-seeded broadleaf weeds. It has been shown that aceto-chlor is very effective on velvetleaf, pigweed species, common ragweed, common lambsquarters, smartweed, and eastern black nightshade as compared to other chlo-roacetamide herbicides. Acetochlor premixes now available in New York provide broad spectrum weed control and can play an important role in herbicide resistance management.

Acetochlor Products Registered in New York State (as of October 15, 2013): Degree® Xtra, Harness®, Harness® Xtra, Harness® Xtra 5.6L, TripleFLEX® and Warrant® are registered trademarks of Monsanto Company

FulTime® NXT, Keystone®, Keystone® LA, Keystone® LA NXT, Keystone® NXT, SureStart®, Surpass® EC, Surpass® NXT are trademarks of The Dow Chemical Company (“Dow”) or an affiliated company of Dow

Integral to the New York State registration, the Acetohchlor Registration Partnership members Monsanto and Dow AgroSciences agreed to implement a product steward-ship program to promote the responsible use of acetochlor products in New York State for protection of water resources. Developed in coordination with Cornell Uni-versity and the New York State Department of Environmental Conservation, the edu-cational outreach reinforces the general responsibility that users have for proper han-dling and application of pesticide products and for acetochlor products specifically. It is expected that this initiative will contribute to the long-term sustainability of weed control options needed for production agriculture in New York.

The foundation of the Acetochlor Stewardship Program for New York is the develop-ment and communication of information which will reinforce the knowledge of farm-ers, dealers, distributors, and custom applicators for responsible use of acetochlor products. Key elements include: (1) Water Quality Best Management Practices for Acetochlor; (2) Acetochlor Stewardship Slide Deck; (3) Quick Reference Card for Label Requirements; and (4) Use of multiple methods and channels for communicating the information including the opportunity for obtaining continuing education credits.

Label Use Restrictions While the Water Quality Best Manage-ment Practices for Acetochlor are a set of voluntary Best Management Practices (BMPs) to reduce the likelihood that acetochlor will impact water resources, an understanding of label use re-strictions is important and is a point of emphasis with the program. Label use restrictions are mandatory requirements and they are summarized below.

Use restrictions common to all aceto-chlor-containing products: Not for Sale, Sale into, Distribution

and/or Use In Nassau and Suffolk Counties of New York State

New York State “Restricted Use” pes-ticide product is restricted in its pur-chase, distribution, sale, use and pos-session, and each product may only be purchased and used by a certified applicator. In addition, any person that distributes, sells, offers for sale, purchases for the purpose of resale, or possesses for the purpose of resale is required to have been issued a com-mercial permit. Atrazine-containing premixes are also Federal Restricted Use Products.

Do not apply directly to water, or to areas where surface water is present or to intertidal areas below the mean high water mark.

Do not flood irrigate to apply or incor-porate.

Do not apply this product through any type of irrigation system, unless oth-erwise directed by approved supple-mental labeling in possession of the user at the time of application.

Do not apply this product using aerial application equipment.

Product must be used in a manner which will prevent: back-siphoning into wells; and spills or improper dis-posal of excess pesticide spray mix-tures or rinsates.

Water Quality BMPs for Acetochlor Water Quality Best Management Practic-es for Acetochlor work in conjunction with the “Core BMPS for All Agricultural Herbicides” currently available on Cor-nell’s Pesticide Safety Education Pro-gram (PSEP) website. They are provided as a series of voluntary options. Produc-ers, crop consultants, and extension spe-cialists should select options most ap-propriate for a given farming operation, soil types and geography, tillage and cultivation practices, and irrigation and runoff management.

The BMP document lists each practice, describes its use along with the benefits of adopting that practice. The BMPs are summarized here: 1. Adopt the “Core BMPs for All Agricul-

tural Herbicides” when applying acetochlor.

2. Limit acetochlor applications to the lowest effective labeled rate.

3. Maintain application setbacks from surface water, tile inlets, wells, and sinkholes as directed by product label.

4. Maintain vegetative filter strips be-tween areas where acetochlor is ap-plied and points where field runoff enters surface water, tile inlets, and sinkholes.

5. Adopt conservation tillage practices appropriate for your farm’s topogra-phy and in karst areas.

6. Use precision application methods.

The Water Quality BMPs for Acetochlor are available at [http://psep.cce.cornell.edu/facts-slides-self/facts/waterquality.aspx]. Always read the product label. Label use require-ments are legally enforceable.

Additional Information Additional information regarding the Acetochlor Stewardship Program is avail-able on-line [http://psep.cce.cornell.edu/facts-slides-self/facts/waterquality.aspx] or by contacting the Monsanto or Dow AgroSciences rep-resentative in your area.

Acetochlor products which also contain atrazine have label use restrictions driven by atrazine requirements. Users must follow the most restrictive requirements on the product labels for applications. The table below summarizes restrictions for atrazine-containing acetochlor products and compares them with acetochlor products not containing atrazine.

Upcoming Meetings

Cornell National GAPs Program, Cornell Vegetable Program, Cornell Lake Ontario Fruit Team, and Cornell Cooperative Extension, along with assistance from NYS Dept. Ag & Markets, will be presenting farm food safety training/GAPs (including Harmonized GAPs) this winter. These workshops are funded through a grant by the Genesee Valley Regional Marketing Authority.

This training is for those farmers who are being required by buyers to provide third party verification of their food safety practices and for farmers thinking about moving in this direction.

The first day of training will focus on the details of what GAPs is, how it works and what it means for your farming operation. The second day will be devoted to helping you write a food safety plan as required for audit certification. A laptop computer is required for the second day.

After attending the 2-day workshop, growers are invited to a mock audit during the growing season so they know what to expect from a third party audit.

For more information or registering online, click on the date of the event (to the left) or contact Craig Kahlke at cjk37@cornell.edu or 585-735-5448.

(For a list of the resistant varieties go to: http://vegetablemdonline.ppath.cornell.edu/NewsArticles/NewsList.htm Scroll down to Tomatoes and click on the article title for the extensive list of tomatoes with resistance. Tobacco mosaic virus (TMV) and Tomato mosaic virus (ToMV) are highlighted in yellow in the variety list. Leaf mold is highlighted in blue. Other resistances are listed but are not im-portant for Northeast tomato growers at this time.)

With ever increasing tomato production shifting to high tunnels and greenhous-es, the importance of identifying tomato varieties with good disease resistance takes center stage. This is particularly true for mosaic virus diseases and leaf mold, two important diseases found in confined production facilities.

strains 0, 1 and 2, have been introduced into many commercial varieties.

Leaf mold has increased in occurrence over the past 5 years with the increase in high tunnel production, lack of heat and over-planting with many indeterminate plants with limited head room creates a perfect moisture environment for this fungus. Formerly called Cladosporium fulvum, it is now known in the vegetable seed industry as causal agent Fulvia fulva (Ff). The resistance genes take their name from the old name of the patho-gen = Cf. Not all identified Cf genes have been used in commercial varieties, but gene Cf-9 is very versatile with re-sistance conveyed to all 5 race groups (A-E). Common occurrence of leaf mold in European greenhouses (mostly un-heated) has contributed to a wide selec-tion of resistant varieties.

Tobacco mosaic virus (TMV) and tomato mosaic virus (ToMV) are two closely re-lated members of the tobamovirus group and share much in common in-cluding being seedborne in tomato and readily spread by normal high tunnel and greenhouse operations (suckering, tying, harvesting). Both remain infectious for long periods, allowing them to survive indefinitely. Seed treatments, sanitation and cross-protection, even with attenu-ated/mild strains of ToMV, have not been totally effective. TMV and ToMV do not cross protect against each other and can coexist in tomato, and they can only be distinguished from each other by se-rological tests and protein composition. It is rare for TMV to be a lasting problem in tomato. ToMV is more adapted to tomato. The use of three dominant re-sistance genes for ToMV (Tm-1, Tm-2 and Tm-22), corresponding to ToMV
